Please help me in these regards,

Well, it is hard to say anything without seeing your code…

Here goes my listen and accept code for TDI server. I don’t know what’s wrong with this code.

NTSTATUS
Listen(PFILE_OBJECT FileObject) //UINT Addr
{
NTSTATUS Status = STATUS_INSUFFICIENT_RESOURCES;
PIRP Irp;
IO_STATUS_BLOCK IoStatus = {0};
PDEVICE_OBJECT DeviceObject;

TDI_CONNECTION_INFORMATION RequestConnectionInfo = {0};
TDI_CONNECTION_INFORMATION ReturnConnectionInfo = {0};

KEVENT Event;

KeInitializeEvent(&Event, NotificationEvent, FALSE);
DeviceObject = IoGetRelatedDeviceObject(FileObject);

Irp = TdiBuildInternalDeviceControlIrp(TDI_LISTEN, DeviceObject, FileObject,
&Event, &IoStatus);
if (Irp == 0)
return STATUS_INSUFFICIENT_RESOURCES;

RequestConnectionInfo.RemoteAddress = NULL;
RequestConnectionInfo.RemoteAddressLength = 0;

TdiBuildListen(Irp, DeviceObject, FileObject, NULL, NULL, TDI_QUERY_ACCEPT, &RequestConnectionInfo, &ReturnConnectionInfo);

Status = IoCallDriver(DeviceObject, Irp);

if (Status == STATUS_PENDING)
Status = KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL); //UserMode

return Status == STATUS_SUCCESS ? IoStatus.Status : Status;

}

/*
* accept
*/

NTSTATUS
Accept(PFILE_OBJECT FileObject)
{
KEVENT Event;
PDEVICE_OBJECT DeviceObject;
IO_STATUS_BLOCK IoStatus;
PIRP Irp;
NTSTATUS Status;

TA_IP_ADDRESS taIpAddress;
TDI_CONNECTION_INFORMATION tdiConnectionInformation;

RtlZeroMemory( &taIpAddress, sizeof( taIpAddress ) );
taIpAddress.TAAddressCount = 1;
taIpAddress.Address[0].AddressLength = TDI_ADDRESS_LENGTH_IP;
taIpAddress.Address[0].AddressType = TDI_ADDRESS_TYPE_IP;

RtlZeroMemory( &tdiConnectionInformation, sizeof( tdiConnectionInformation ));
tdiConnectionInformation.RemoteAddressLength = sizeof( taIpAddress );
tdiConnectionInformation.RemoteAddress = &taIpAddress;

KeInitializeEvent(&Event, NotificationEvent, FALSE);
DeviceObject = IoGetRelatedDeviceObject(FileObject);

Irp = TdiBuildInternalDeviceControlIrp(TDI_ACCEPT, DeviceObject, FileObject,
&Event, &IoStatus);
if (Irp == 0)
return STATUS_INSUFFICIENT_RESOURCES;

TdiBuildAccept(Irp, DeviceObject, FileObject, NULL, NULL, &tdiConnectionInformation, 0);

Status = IoCallDriver(DeviceObject, Irp);

if (Status == STATUS_PENDING)
Status = KeWaitForSingleObject(&Event, UserRequest, KernelMode, FALSE, 0);

return Status == STATUS_SUCCESS ? IoStatus.Status : Status;

}
